The Culligan EZ-4 under-sink water filtration system delivers cleaner, better-tasting drinking water straight from a dedicated chrome faucet on your countertop. This system connects directly to your cold water line and uses premium filtration technology to reduce chlorine taste and odor, sediment, and other common contaminants that affect water quality. Installation is straightforward with included components, and the compact under-sink design keeps your filtration out of sight while the polished chrome faucet adds a clean, modern touch to your kitchen.
The EZ-4 filter cartridge provides up to 500 gallons of filtered water or approximately six months of typical household use before replacement.
